My dad ignores mental illness. How do I deal?

My dad REFUSES to speak about mental illnesses and mental health. He thinks it’s ridiculous and not true. I think he’s honestly afraid of it. I’m currently getting my bachelors in psychology and I often speak about my own mental issues with anxiety, depression and recovered eating disorder; as well as my young sisters ADHD. MENTAL HEALTH SHOULD BE SPOKEN ABOUT! It is the same as having kidney issues!! Your brain is an organ that is capable of disorders and illness.

His quote was “Like Morgan Freeman once said, “in order for it to go away we must stop talking about it.” He compared that quote to mental illness. Like... what? I truly think he’s so scared of going CRAZY. If anything, speaking about it helps us understand it and cope/heal. Please tell me my dad isn’t the only one 😭
